Botha had the better skills but Chisora was more physical. I think the best version of Chisora wears Botha down, probably.
Botha by UD but I won't count Chisora out. Botha was durable, quite slick in his own way and had great timing.
Botha gave Moorer a very competitive fight for 11 rounds. Botha was robbed of a decision vs Briggs. Botha won every round against a past it but still dangerous Tyson until he got caught with a punch out of nowhere. Botha is of a similar level to Chisora and really it could go either way.
